Abstract
Silylamines add to alpha,beta-unsaturated aldehydes and ketones in 1,4 -addition mode to generate amino-substituted silyl enol ethers without any catalysts. These easily isolable silyl enol ethers react with ace tals and aldehydes in the presence of a Lewis acid to give alpha-alkox yalkyl and alpha-hydroxyalkyl substituted alpha,beta-unsaturated carbo nyl compounds, respectively, after deamination by treatment with silic a gel.
